2 months agoMerge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"
Tom Rini [Fri, 11 Oct 2024 18:23:25 +0000 (12:23 -0600)]
Merge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"

Simon Glass <sjg@chromium.org> says:

When the SPL build-phase was first created it was designed to solve a
particular problem (the need to init SDRAM so that U-Boot proper could
be loaded). It has since expanded to become an important part of U-Boot,
with three phases now present: TPL, VPL and SPL

Due to this history, the term 'SPL' is used to mean both a particular
phase (the one before U-Boot proper) and all the non-proper phases.
This has become confusing.

For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL'
phases, not just SPL. So code which can only be compiled for actual SPL,
for example, must use something like this:

   #if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD)

In Makefiles we have similar issues. SPL_ has been used as a variable
which expands to either SPL_ or nothing, to chose between options like
CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable
was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was
updated to support 'VPL_' as well.

This series starts a change in terminology and usage to resolve the
above issues:

- The word 'xPL' is used instead of 'SPL' to mean a non-proper build
- A new CONFIG_XPL_BUILD define indicates that the current build is an
  'xPL' build
- The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now
  defined for TPL and VPL phases
- The existing SPL_ Makefile variable is renamed to SPL_
- The existing SPL_TPL Makefile variable is renamed to PHASE_

It should be noted that xpl_phase() can generally be used instead of
the above CONFIGs without a code-space or run-time penalty.

This series does not attempt to convert all of U-Boot to use this new
terminology but it makes a start. In particular, renaming spl.h and
common/spl seems like a bridge too far at this point.

The series is fully bisectable. It has also been checked to ensure there
are no code-size changes on any commit.

This series is a reworked version of the previous seried:
misc: introduce STATUS LED activity function

This series port and expand the legacy concept of LED boot from
the legacy Status LED API to new LED API.

One thing that many device need is a way to communicate to the
user that the device is actually doing something.

This is especially useful for recovery steps where an
user (for example) insert an USB drive, keep a button pressed
and the device autorecover.

There is currently no way to signal the user externally that
the bootloader is processing/recoverying aside from setting
a LED on.

A solid LED on is not enough and won't actually signal any
kind of progress.
Solution is the good old blinking LED but uboot doesn't
suggest (and support) interrupts and almost all the LED
are usually GPIO LED that doesn't support HW blink.

Additional Kconfg are also introduced to set the LED boot and
activity. Those are referenced by label.

A documentation for old and these new LED API is created.

The clk command cannot provide useful output without a clock driver.
So let it depend on CONFIG_CLK.

Since commit 258c1002383e ("cmd: clk: Use dump function from clk_ops")
the remark about deprecation is obsolete. Remove it.

Since commit 7ab418fbe612 ("clk: add support for setting clk rate from
